Description

Technical Field

[0001] The utility model relates to the technical field of ball screw pairs, in particular to a ball screw pair structure using a lubricating oil tank. Background Art

[0002] Referring to the application number "CN202020619766.9", the patent document named "A ball screw pair structure using a lubricating oil tank" allows the lubricating oil inside the oil tank to contact the screw through the felt. When in use, the nut and the screw produce relative displacement. The lubricating oil can lubricate the screw through the felt, reducing the friction resistance of the displacement, extending the service life of the ball screw pair, and it can be used for a long time after one filling, reducing the frequency of filling and improving production efficiency.

[0003] The prior art achieves normal operation of the screw through a lubricating oil tank, and the felt can improve the long-lasting benefits of the lubricating oil, which can effectively improve the operating efficiency of the ball screw. Although the lubricating oil tank of the prior art can extend the operating efficiency of the ball screw, the ball screw will cause the lubricating oil to extend to the bottom periphery under continuous action, and combine with the dust in the base to produce dirty oil, and cause the ball screw to partially lose its lubrication effect, thereby reducing the lubrication effect of the ball screw.

[0004] To this end, we designed a ball screw pair structure using a lubricating oil tank. Utility Model Content

[0013] The beneficial effects of the utility model are:

[0014] 1. The utility model can effectively improve the lubrication effect of the lead screw during operation by setting a block and a connecting clamp. At the same time, the dirty oil produced on the lead screw can be effectively blocked by the block, reducing the re-combination of the dirty oil and the lubricating oil to produce more dirty oil. At the same time, the connecting clamp can effectively increase the lubrication area of ​​the lead screw surface. Compared with the prior art, the lubrication effect of the lead screw surface can be improved. At the same time, the block can also reduce the hindrance of the dirty oil to the operation of the lead screw and avoid the local loss of lubrication of the lead screw, thereby improving the lubrication effect of the lead screw.

[0015] 2. The utility model improves the braking effect between the connecting clamp and the blocking block by setting the liquid guide angle and the liquid retention groove, reduces the contact of the lubricating oil with the external environment, and retains it in the third slide groove to improve the lubrication effect of both. Compared with the prior art, it can effectively improve the application of missed lubricating oil, avoid the waste of lubricating oil and the formation of stained oil combined with the external environment. At the same time, the lubricating body can effectively prevent the evaporation of lubricating oil on the surface of the screw. Compared with the effect of the felt in the prior art, it can effectively prevent the felt from generating heat due to excessive contact with the screw and causing the evaporation of the lubricating oil, thereby improving the retention effect of the lubricating oil.

DETAILED DESCRIPTION

[0021] Reference Figure 1-Figure 4 A ball screw pair structure using a lubricating oil tank includes a mounting base 1, which is a basic component used in the prior art for mounting a ball screw on a component, a ball screw 4 is a ball screw pair fixed on the mounting base 1 in the prior art, a front plug 2 is a front end of the mounting base 1 in the prior art, which is mainly used to limit the moving distance of the screw 4 and prevent the screw 4 from derailing, a rivet is a tool used in the prior art for fixing metal components to each other, and an engine rear plug 3 is a motor structure on the mounting base 1 in the prior art, which is mainly used for the braking operation of the screw 4.

[0022] The lead screw 4 is provided with a block 6 for blocking stains. The block 6 is a rectangular block made of aluminum alloy material. It is mainly used to reduce the stain oil body generated by the combination of residual lubricating oil and stains on the lead screw 4, so as to prevent the stain oil body from interfering with the operation and lubrication effect of the lead screw 4. The block 6 is adapted to the lead screw 4. The lead screw 4 passes through the block 6 and slides on the limiting strip 5. The block 6 is provided with a lubricating body 7 for increasing the coverage of the lubricating oil. The lubricating body 7 is made of rubber material, which can effectively improve the lubrication effect of the lubricating oil and the lubrication effect of the lead screw 4. The lubricating body 7 is provided with a plurality of sponge grooves for reducing oil evaporation. The sponge grooves are opened at the bottom of the lubricating body 7, which can effectively store the lubricating oil to prevent evaporation.

[0023] The mounting base 1 is provided with a limiting strip 5 for limiting the direction of the blocking block 6. The limiting strip 5 is mainly used to control the direction correction of the blocking block 6, the lubricating body 7 and the sliding block 8 to avoid the deviation of the lead screw 4 caused by errors during its operation. The two ends of the limiting strip 5 are fixedly connected to the front plug 2 and the engine rear plug 3 by welding. Welding can improve the connection strength between the two. The top of the limiting strip 5 is adapted to the blocking block 6, and the bottom of the blocking block 6, the lubricating body 7 and the sliding block 8 are provided with a slot for adapting the limiting strip 5, and are adapted to the lubricating body 7.

[0024] An oil storage tank 10 for improving the lubrication effect of the screw 4 is symmetrically arranged on the block 6. The oil storage tank 10 is a lubricating oil tank in the prior art, which is mainly used to store lubricating oil and supply lubricating oil to the screw 4. The oil storage tank 10 is against the screw 4 through a connecting clamp 9. The connecting clamp 9 is made of a wetted material, which can effectively pass the lubricating oil through the operation friction of the screw 4 and retain it on the surface of the screw 4. The connecting clamp 9 is adapted to the limiting strip 5 through a slider 8. The slider 8 is an auxiliary sliding component in the prior art, and a contact end for improving the lubrication of the screw 4 is provided on the connecting clamp 9.

The first slide groove 11 is adapted to the oil storage tank 10. The first slide groove 11 is provided on both sides of the mounting base 1. The first slide groove 11 is mainly used to reduce the friction between the oil storage tank 10 and the mounting base 1, which causes the bottom of the oil storage tank 10 to become thinner and leak.

[0026] A third slide groove 13 for temporarily storing lubricating oil is symmetrically provided on the limiting strip 5. The second slide groove 12 is mainly used to control all the components on the limiting strip 5. A second slide groove 12 for improving the operation effect of the connecting clamp 9 is provided on the limiting strip 5. The second slide groove 12 is used to enhance the control of all components on the limiting strip 5 and make them all consistent with the direction of the lead screw 4. The third slide groove 13 is adapted to the block 6 and the connecting clamp 9. A liquid inlet angle 14 for guiding the lubricating oil is provided on the third slide groove 13. The liquid inlet angle 14 is mainly used to prevent the lubricating oil remaining on the limiting strip 5 from extending to the surface of the mounting base 1, causing oil stains on the mounting base 1 and obstructing its operation. A liquid retaining groove 15 for retaining lubricating oil is provided on the third slide groove 13. The liquid retaining groove 15 is used to temporarily store the residual lubricating oil, so that it can contribute to the lubrication effect of all components in the third slide groove 13, reduce the friction between them and the limiting strip 5, and thus improve the service life of the limiting strip 5.

[0027] The working principle of the utility model is as follows: the mounting base 1 is fixed to the placement surface, and the engine rear plug 3 is connected to the power supply. Then, under the operation of the screw 4, the oil storage tank 10 continuously puts the lubricating oil on the surface of the screw 4 and improves the operation effect of the screw 4. The blocking block 6 can increase the contact between the stained oil body on the screw 4 and the lubricating oil, and improve the operation effect of the screw.
